I am a pretty big believer in 2 3/4” copper plated 6s. Usually I carry a 20ga but will take the 12 pretty much all of December – that’s when I break out the 3” 4s as my last few shots.
WPAs get blackcloud 4s all season.
Kent 3″ bismuth 5s with an IC choke. Kind of overkill, have to be a little careful about ones jumping at your feet and give them a second but never really had a problem.
